How To Care

When planting your Nikko Blue Hydrangea be sure you have the right location and conditions for your new plants to thrive. Spring and Fall are ideal times to plant Hydrangeas. Avoid planting hydrangeas in summer when temperatures are mid80s or higher.

The Nikko Blue Hydrangea requires full sun to part shade and prefers moist, well-drained, fertile, acidic soil. In hot climates, hydrangeas will do best with some shade. If you have alkaline soil, be sure to amend your soil to maintain the deep blue color. To acidify your soil, amend with compost, elemental sulfur, or use fertilizers specific for acid loving plants. Mulching with pine straw or pine bark will help over time as they begin to break down, they will naturally add acidity to the soil. Keep the soil moist, but not saturated, especially in summer and in the first year after planting. Throughout its life Hydrangeas will do best with a deep watering once weekly during hot temperatures.Mulching at about 3 inches deep is highly recommended for hydrangeas. Mulching will cut back on watering needs and protect your plant in extreme temperatures. Choose a slow release fertilizer for acid loving plants. Fertilize once in spring after the last chance of frost and again in early summer for best results. You don’t need to prune hydrangeas, but pruning after they are done blooming can help encourage a bushier growth and renew an older plant.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. You can treat mites, scale, whiteflies, and aphids naturally with neem oil or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. Fungal infection can be prevented by making sure the planting site has good drainage and by avoiding overhead watering. Fungal infections can be treated with a fungicide. Generally, treating fungus after infection isn't effective so if you have problems with other plants or in a prior year, treat preventatively in early spring.

Nikko Blue Hydrangas

They arrived very bent and damaged. Most of the leaves looks as though they had insects eating them. The leaves also have some sort of Disease that appears to be spreading. I’ve planted them and watered them daily hopeful they will overcome what ever shock etc...they’ve suffered. Could you provide any advise as to how to keep them alive?

Love the plants..

Well packed in large tall shipping containers...which were on their sides...not upright. Thus roots of plants broke off and plants fell out of planter! No marks on shipping boxes to say to keep upright! Only hope the plants make it...Green and lush!

Nikko Blue

Great experience. Just like my azalea purchase, the hydrangea was very healthy and well packed. It arrived totally undamaged and now resides in a prime location in my garden.
